the kit arrived a week in advance, and is perfect for my Ender 3 Pro. There are no assembly instructions, but it is easy and intuitive, in case of difficulty just see how the original piece is assembled. The spring is a little stronger than the original one and it is now much easier to load the filament. I'm really happy. The kit arrived a week in advance, and is perfect for my Ender 3 Pro.

very great package that fulfilled my first level of needs. The delivery was faster then expected and it all worked out well, although a manual for parts of it would have been nice.

Much better printing! Instalation is easy! Recomended! Very fast shipping!

The spring of the extruder is very hard. If you like it, full throttle. otherwise just take the old spring. top extruder 👍 the springs are also class

the metal extruder upgrade is mandatory after a few weeks of use of the printer. this is very easy to install.

Firm springs and quality extruder kit. I had no problem getting parts wrong or incomplete.

Perfect for ender 3 v2.

Great product to keep my 3d printer health

great upgrade, much better than the plastic ones. I fitted to enter 3 pro. easy to fit and easier to install element.

4,5 months to delivery, but it works good
